Assuming that the measures given in the question refer to the lengths of the sides of the rectangle, the answer is 40 metres.
8m 8m 12m 3m
98
96
20m
The area of rectangle is : 96.0
Perimeter = 12+12+3+3 = 30m
Perimeter=2(l+b) =2*6 =12m
The perimeter is 12m
8m*5m=40 m2 The area of the rectangle is 40m2
The area of rectangle is : 96.0
40 m
Area = 12*8 = 96 square m
what is the perimeter of a rectangle 8mm by 3m
Perimeter is 36 mArea is 72 square m
12m
If you put an ant down on the rectangle and start him walking along the line, the 'perimeter' is the distance he has to walk in order to get back to where he started, if he stays on the line. If you put him down on a corner of this one, he has to walk (8m + 3m + 8m + 3m) = 22m. That's the perimeter.
Perimeter = 12+12+3+3 = 30m
Isn't it the sum of all sides? 8m+8m+3m+3m = 22m
Perimeter=2(l+b) =2*6 =12m
There cannot be a 12m rectangle. A rectangle is a two dimensional object and so there must be two linear measures to describe it. Either there is measure of another length, for example a 12m x 8m rectangle. In that case the question is redundant. Or the 12m is intended as a measure of area and should actually have been 12 SQUARE metres. However, in that case, there are infinitely many possible solutions.
Perimeter = sum of all sides Sides = 4.5m, 4.5m, 1.5m, 1.5m Total = 12m
